黄酮类化合物按其基本骨架分类可分为:黄酮(flavone),黄酮醇(flavonol),二氢黄酮(flavanone),二氢黄酮醇(flavanonol),异黄酮(isoflavone),查耳酮(chalcone)和橙酮(aurone)等主要几类。在上述几类黄酮类化合物中,有的是已知药物;还有一些已被证明是中草药中的有效成分。因此对黄酮这一大类天然有机化合物的鉴别和结构测定无疑在药物研究和天然化合物研究中具有十分重要的意义。近几年,国内很多科研院所,大专院校都有傅立叶变换核磁共振仪(FT-NMR).这为药 Flavonoids can be classified according to their basic skeletons: flavone, flavonol, flavanone, flavanonol, isoflavone, chalcone, And aurone (aurone) and other major categories. Among the above flavonoids, some are known drugs; others have been shown to be active ingredients in Chinese herbal medicine. Therefore, the identification and structure determination of natural organic compounds in flavonoids is undoubtedly of great significance in the study of drugs and natural compounds. In recent years, many domestic research institutes and tertiary institutions have Fourier transform nuclear magnetic resonance (FT-NMR)
